Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595552, here are decompositions:

181 + 31595371 = 31595552
379 + 31595173 = 31595552
691 + 31594861 = 31595552
739 + 31594813 = 31595552
823 + 31594729 = 31595552
853 + 31594699 = 31595552
1051 + 31594501 = 31595552
1063 + 31594489 = 31595552

Showing the first eight; more decompositions exist.
